Heterozygotes segregate wild-type GFP+ heterozygotes, GFP+ Dpy, and sec-5 homozygotes (scrawny, small broods, abnormal gut appearance) sec-5 is homozygous maternal-effect lethal; M+Z- animals produce a few dead L1-L2 stage larvae with Vab defects. Pick GFP+ wild-type to maintain. Based upon phenotype, pk2357 is a strong loss-of-function, but likely not a null allele; molecular lesion produces a premature stop at position 389. Reference: Frische EW, et al. EMBO J. 2007 Dec 12;26(24):5083-92. [NOTE: This strain was previously described as carrying pk2358, but pk2357 is the correct allele. Both pk2357 and pk2358 cause the same nonsense (amber) change.]

xnIs461 [sec-5::YFP + unc-119(+)]. Expresses sec-5::YFP maternally and zygotically. Expression is present in many cells, including early embryos, epithelial cells, the excretory cell, and the germ line. Rescues maternal-effect lethality of sec-5(pk2358).
